Penis is one of the most important components of male external genitalia.Congenital abnormalities and trauma may lead to genitourinary organ damage or default,which require reconstruction.With the development of tissue engineering(TE),penile corpora cavernosa tissue engineening has becoming the core of the penis reconstruction.Recent researches mainly focus on forming scaffolds and transplanting cells(including of endothelial cells and caveruosal smooth muscle cells). Recently, stem cell technology, gene therapy and nervous reconstructive techniques have been combined to promote the development of tissue engineering.Tissue engineering has been thought to be able to make possible the restoring and constructing of the structure and normal funetion of penile corpora cavernosa.This paper gives a review of the recent progress in associated researches on tissue engineering of the penile corpora cavernosa.

Baculoviruses are a family of arthropod-specific viruses that produce two morphologically distinct types of virions (budded and occlusion-derived) in their lifecycle. Baculoviruses establish infection in the midgut of their host via the oral route: occlusion-derived virions have pivotal roles in these processes. This review summarizes the basic characteristics of baculoviruses, and discusses the composition and classification of baculovirus occlusion-derived virions. The latter focuses mainly on the evolution and role of multiple occlusion-derived virions in the lifecycle of baculoviruses. These achievements should aid understanding the evolution and infection mechanisms of baculoviruses.

Objective To compare the consumption of the drugs for patient-controlled intravenous analgesia (PCIA) in patients with different blood groups. Methods One hundred female ASA Ⅰ or Ⅱ patients, aged 30-50 yr, body mass index ＜ 30 kg/m2 , scheduled for elective total hysterectomy or myomectomy, were enrolled in this study. The patients were divided into 4 groups according to the blood group: group A ( n= 25), group B ( n = 30), group AB ( n = 11 ) and group O ( n = 34). Patients received iv injection of flurbiprofen 30 min before the end of surgery and sufentanil at the end of surgery. PCIA with sufentanil 1.2 μg/ml ( bolus dose 2.0 ml, background infusion 0.5 ml/h, lockout interval 5 min) was performed when the VAS score ≤4. The loading dose and consumption on 1 st and 2nd day after operation for sufentanil were recorded. The adverse reactions were observed.Results The loading dose and consumption on 1st day after operation for sufentanil were the highest in group A and B, the second in group AB, and the lowest in group O among the 4 groups. Conclusion The consumption of the drugs for PCIA is different in patients with different blood groups.

A part of pathogenetic factors of hypertensionin twenty--seven patients with hypertensive NIDDM (group 1) were observed. The control groupsincluded non-hypertensive NIDDM (group 2, n=46 ), primary hypertension (group 3, n= 15) andhealthy persons (group 4, n= 15). The oral glu-cose tolerance test (OGTT), insulin releasing test(IRT ), atrial natriuretic peptide (ANP), an-giotensin I (ATI), aldosterone (ALD), wholeblood volume and urine protein were measured.The results showed that the plasma insulin andsodium levels and the whole blood volume weresignificantly higher in group 1 than those in con-trol group 2, the ANP level was rather lower than that in control group 4. Although the results werecorresponded with the theory that the circulatinghyperinsulinemia may lead to sodium retention andinhibited an adequate ANP stimulation by sodiumchallenge which turn to hypertension, nonhyper-tensive NIDDM patients (group 2) also have thesame findinge. So the retention of sodium and wa-ter can't be used to explain the mechanism of hy-pertension in NIDDM patients, the other patho-genetic factors especialy the factors related to thehyperinsulinemia such as PGE and PGI need to beinvestigated futher.

The purpose of this study is to ascertain the significance of diagnosis of human papillomavirus (HPV) infection and the histological pattern of distriution of HPV in condylomata acuminata(CA) by direct in situ PCR (ISPCR) technique. of the 25 patients with BA, all 10 cases with typical histopathological features of CA gave a positive reaction in tile upper layers of the epithelium. HPV was also detected in the granular ladyer and whole prickle cell layer of 11 cases of CA with no typical koilocytes. In the direct ISPCR oligonucleotides labelled with bio tin were incorporated in situ during amplification, then immunohistochemical method was used for detection. In this technique the viral existence in paraffin sections can be directly compared with the histologic changes, and can help pathologist to analyze the possibility that HPV is present in the suspected lesions.

Objective To explore the effects and safety of low-frequency repetitive transcranial magnetic stimulation (rTMS) on treating tinnitus.Methods A total of 102 normal hearing patients with tinnitus underwent active rTMS in the left temporoparietal region.Repetitive TMS consisted of 1 000 stimulations at 1 Hz daily and 110% of the motor cortex threshold for 5 consecutive days per week (Monday to Friday) for 2 weeks.A visual analog scale (VAS) was used to assess tinnitus loudness.All participants were interviewed regarding age, gender, tinnitus duration, laterality and pitch etc.Results Low-frequency rTMS significantly decreased tinnitus in the head after the active stimulation.After rTMS treatments, 34 cases of tinnitus in the head showed an effective rate of 70.6%, in which 2 patients reported complete tinnitus disappearance (5.9%), 22 cases had significantly reduced effect.Sixty-eight patients in the control group showed an effective rate of 64.7%, in which 1 case''s tinnitus disappeared (1.5%) and 43 cases significantly reduced.According to the results of PTA,the hearing thresholds of the two groups had no significant difference between before and after the treatment.There were no headaches, dizziness, nausea, drowsiness, burns, seizures in all the patients after treatment.Conclusion Active low-frequency rTMS resulted in a significant reduction in the loudness of tinnitus in the head.
